I build wordpress website with aws lightsail hosting.

I bought my domain in GoDaddy and created custom email with the domain (info@myDomain.com) – myDomain is just for the explanation.

I’m trying to configure contact form and send emails to this email.

so what I did is installed WP Mail SMTP and configure the settings.
into settings what I set is

then in SMTP Host I added

I saved the settings and send email test – I’m getting the error

There was a problem while sending the test email.

I tried more different smtp hosts:

  1. smtpout.secureserver.net with port 465/587
  2. https://email.secureserver.net
  3. myDomain-com.mail.protection.outlook.com

nothing helped – I get the same error.

in GoDaddy I found this for my domain

I talked with GoDaddy customer service for over then 3 hours- they didn’t know how to help me.
I read some tutorials such as:

https://il.godaddy.com/en/help/send-form-mail-using-an-smtp-relay-server-953

I still looking for any answer.

  1. From Remove port 25 restriction from your Lightsail instance:

    By default, AWS blocks outbound traffic on port 25 on all Lightsail instances. To send outbound traffic on port 25, request that this restriction be removed.

    You will need to request for the restriction to be removed.

    Alternatively, connect to an SMTP server via a different port (which is common when using TLS).

  2. As Lightsail blocks outbound traffic on port 25. tried port number 2525.
